Radical SBr: a challenge to spectroscopists?
نویسنده
چکیده
A theoretical description of the electronic states of the SBr radical at a high level of correlation effects treatment is presented for the first time. Most of its potential energy curves have a repulsive nature, but a set of bound (2)Pi states should provide a means for the experimental characterization of this species. The ground state can support over 40 vibrational states, but transitions from the 2 (2)Pi state, with a very shallow well (four levels), should have intensities spread over a maximum around v(")=10; lower vibrational levels can only be accessed for transitions from two high-lying Rydberg states. A whole set of spectroscopic constants, including vibrationally averaged spin-orbit coupling constants, and radiative transition probabilities and lifetimes quantify the theoretical description, thus supplying reliable results to guide the experimental investigation of this species.

Evaluation of simultaneous nutrient removal and sludge reduction using laboratory scale sequencing batch reactors.
The treatment and disposal of excess sludge has been a rising challenge for wastewater treatment plants worldwide. In this study, simultaneous sludge reduction and nutrient removal was evaluated in laboratory scale sequencing batch reactors (SBRs). Two SBRs were operated alongside for a duration of 370d. One SBR was operated to achieve nutrient removal (control-SBR) at 10d solids retention time...
متن کاملOn-line Nonlinear Process Monitoring of a Pilot-scale Sequencing Batch Reactor
This article describes the application of on-line nonlinear monitoring of a sequencing batch reactor (SBR). Three-way batch data of SBR are unfolded batchwisely, and then a nonlinear multivariate monitoring method is used to capture the nonlinear characteristics of normal batches. The approach is successfully applied to an 80L SBR for biological wastewater treatment, where the SBR poses an inte...
متن کاملHDR brachytherapy as a solution in recurrences of locally advanced prostate cancer
PURPOSE The object of this study was to analyze the outcome of salvage HDR brachytherapy treatment after local failure, for patients with prostate specific antigen (PSA) failure without distant metastasis, after external beam radiation and HDR brachytherapy treatment, or after radical prostatectomy, with or without hormonal therapy. MATERIAL AND METHODS The group of 115 patients, without dist...
متن کاملComparing surface-based and volume-based analyses of functional neuroimaging data in patients with schizophrenia
A major challenge in functional neuroimaging is to cope with individual variability in cortical structure and function. Most analyses of cortical function compensate for variability using affine or low-dimensional nonlinear volume-based registration (VBR) of individual subjects to an atlas, which does not explicitly take into account the geometry of cortical convolutions. A promising alternativ...
متن کاملDirect Administration of Nerve-Specific Contrast to Improve Nerve Sparing Radical Prostatectomy
Nerve damage remains a major morbidity following nerve sparing radical prostatectomy, significantly affecting quality of life post-surgery. Nerve-specific fluorescence guided surgery offers a potential solution by enhancing nerve visualization intraoperatively. However, the prostate is highly innervated and only the cavernous nerve structures require preservation to maintain continence and pote...
